Children are becoming less physically active than they were in the past. Many are staying indoors longer to watch TV and play videogames, and parents may be less eager to have their children running around outside due to fear of abduction or traffic accidents. As these trends have increased (and as diets have become less healthy), there has been a dangerous rise of obesity in children in recent years.
Childhood obesity should be taken very seriously -- many obese children develop type 2 diabetes, high cholesterol and blood pressure, sleep apnea, orthopedic problems, and other conditions that can last into adulthood.
The remedy for obesity is a nutritious diet and at least 60 minutes of moderate physical activity on most days of the week. Children may, however, need as much as 2 hours of physical activity a day. Adolescents may need 1.5 hours of physical activity a day.
Your child can jump, play basketball, participate in running games, bike, or find any other way to be active and have fun. For the health of your child, the Agency for Health Care Policy and Research makes the following suggestions to help develop good physical activity habits.
- Encourage your child to participate in physical activities, including sports.
- Encourage involvement in activities that can be enjoyed into adulthood (walking, running, swimming, basketball, tennis, golf, dancing, and bicycle riding).
- Plan physical activities with family or friends. Exercise is more fun with others.
- Limit the time your child spends watching TV to less than 2 hours per day. Encourage going out to the playground, park, gym, or swimming pool instead.
- Physical activity should be fun. Don't make winning the only goal.
- Many communities and schools offer exercise or sports programs. Find out what is available for your child.
- Created by the Agency for Health Care Policy and Research.
Remember, your children learn many of their habits from you. Try to set a good example and give them plenty of encouragement. You will be helping to give them a lifelong gift of good health.
The chances for heart disease may start to develop in children as early as elementary school. Children who exercise at least 2 hours a day, however, have a lower risk for heart disease than those who do not exercise. Adolescents who exercise at least 1.5 hours a day have a lower risk for heart disease.
